 *
 * #WebKitWebView is the central class of the WebKitGTK+ API. It is a
 * #GtkWidget implementing the scrolling interface which means you can
 * embed in a #GtkScrolledWindow. It is responsible for managing the
 * drawing of the content, forwarding of events. You can load any URI
 * into the #WebKitWebView or any kind of data string. With #WebKitWebSettings
 * you can control various aspects of the rendering and loading of the content.
 * Each #WebKitWebView has exactly one #WebKitWebFrame as main frame. A
 * #WebKitWebFrame can have n children.
 *
